Hi, I am trying to start the VNC session from Ubuntu 18.04 but I am having the error message attached here.

It was alright till I was working on my last session, but as soon as that ended I am unable to connect again. I also tried using the SSH command which is working fine.

Having conda environment in your .bashrc is known to cause conflicts with VNC. The easy fix would be to login via ssh and check your ~/.bashrc file and delete everything except:

> ```
> # .bashrc
> # Source global definitions
> if [-f /etc/bashrc]; then
> . /etc/bashrc
> fi
> 
> ```

Give this a try and let us know if you encounter any issues.
